Abstract

The invention is based on a pneumatic vehicle tyre with a carcass whose ends are anchored in the beads by wrapping the bead cores. In order to be able to bring about tread-reinforcement of the carcass, in particular in the tyre, according to the invention the ends of the carcass are doubled by folding back.

Description

Die Erfindung betrifft einen Fahrzeugluftreifen mit einer Karkasse, deren Enden durch Umschlingen der Wulstkerne in den Wülsten verankert sind.The invention relates to a pneumatic vehicle tire with a carcass, the ends of which are anchored in the beads by wrapping the bead cores are.

Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, eine besonders kräftige Karkaßverstärkung, insbesondere für Fahrradreifen zu schaffen. Die Herstellung soll dabei in einfacher Weise erfolgen können.The invention is essentially based on the task, a particular one strong carcass reinforcement, especially for bicycle tires create. The production should take place in a simple manner can.

Zur Lösung dieser Aufgabe sind erfindungsgemäß die Karkaßenden gedoppelt und zudem befinden sich die freien Karkaßenden oberhalb der Wulstpartie.To achieve this object, the carcass ends are doubled and also the free carcass ends are above the Bead section.

In einfacher Weise wird somit ein sogenannter 4-Lagenfuß geschaffen. Dies ist aufgrund der Erfindung dadurch möglich, daß die Karkaßenden gedoppelt werden und diese gedoppelten Enden um die Wulstkerne herumgeführt werden, wenn die Reifenherstellung erfolgt.A so-called 4-layer base is thus created in a simple manner. This is possible due to the invention in that the carcass ends be doubled and these doubled ends are led around the bead cores when the tire is manufactured.

Wichtig ist dabei ferner, daß der oberhalb der Kerne befindliche frei auslaufende Teil der Karkasse keine frei auslaufenden Fadenenden aufweist, sondern die durch die vorgenannte Herstellung bedingte Umlenkstelle der Karkaßfäden.It is also important that the one above the cores is free part of the carcass that runs out has no free thread ends, but the deflection point caused by the aforementioned production the carcass threads.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist. Further details of the invention are explained with reference to the drawing, in which an embodiment of the invention is shown.  

Die Abbildung zeigt einen Querschnitt durch einen Fahrradreifen.The illustration shows a cross section through a bicycle tire.

Der im wesentlichen aus Gummi oder gummiähnlichen Kunststoffen bestehende Luftreifen hat in seinen Wülsten 1 Stahlkerne 2, die zur Verankerung der Karkasse dienen, welche in üblicher Weise aus einem gummierten Gewebe besteht. Diese Karkasse wird gebildet von einer inneren Lage 3, die ununterbrochen von einem Wulst 1 zum anderen geführt ist, und einer äußeren Lage, die aus zwei Abschnitten 4 und 5 besteht, welche vom zugehörigen Wulst 1 zur abgekehrten Schulter des Laufstreifens 6 geführt sind in der Weise, daß sich die Abschnitte 4 und 5 im Laufstreifenzenit etwa über die Breite der Lauffläche überlappen.The pneumatic tire consisting essentially of rubber or rubber-like plastics has in its beads 1 steel cores 2 which serve to anchor the carcass, which in the usual way consists of a rubberized fabric. This carcass is formed by an inner layer 3 , which is continuously guided from one bead 1 to the other, and an outer layer, which consists of two sections 4 and 5 , which are guided from the associated bead 1 to the opposite shoulder of the tread 6 in the Way that sections 4 and 5 overlap in the tread width approximately by the width of the tread.

Die Karkaßverankerung erfolgt durch Herumführen der Karkaßabschnitte 3, 4 und 5 um die Wulstkerne 2. Diese Karkaßelemente sind jedoch oberhalb der Wülste 1 nicht frei auslaufend, sondern miteinander vereinigt ausgebildet. Das heißt: Zu beiden Seiten der Wulstpartien sind frei auslaufende Enden von Karkaßabschnitten nicht vorgesehen.The carcass is anchored by moving the carcass sections 3, 4 and 5 around the bead cores 2 . However, these carcass elements are not designed to run out freely above the beads 1 , but rather are combined with one another. That means: Free ends of carcass sections are not provided on both sides of the bead parts.

Die Herstellung dieser Reifen, insbesondere die Herstellung der Karkassen ist dadurch möglich, daß man ein zunächst flach ausgebreitetes Gewebe zur Mitte hin überfaltet, um so die Überlappungsstelle zwischen den Abschnitten 4 und 5 zu bilden. Alsdann werden die Kerne gesetzt, worauf die gedoppelten Ränder um die Wulstkerne 2 herumgeführt und der Reifenrohling durch Bombieren fertiggestellt wird.The manufacture of these tires, in particular the manufacture of the carcasses, is possible by folding an initially flat fabric to the center, so as to form the overlap between the sections 4 and 5 . Then the cores are set, whereupon the double edges are led around the bead cores 2 and the green tire is finished by crowning.
